Embodiment 1

[0046] In Embodiment 1 of the present invention, during the process of the terminal talking or initiating a call, according to whether the distance between the specified area on the terminal screen and the human body is greater than the distance threshold, the screen is controlled to turn off and turn on. It is determined based on the contact capacitance generated by the screen when the specified area on the screen is close to the human body.

[0047] For example, taking a capacitive touch screen as an example, when the human body touches the capacitive sensing area on the screen, the electric field of the human body will form a coupling capacitance with the surface of the touch screen. In essence, when there is no contact between the human body and the screen, but close to a certain degree, coupling capacitance will be generated.

Embodiment 2

[0059] In Embodiment 2 of the present invention, during the process of the terminal talking or initiating a call, according to whether the distance between the specified area on the terminal screen and the human body is greater than the distance threshold, the screen is controlled to turn off and turn on. It is determined based on the supplementary current of the touch capacitance generated by the screen when the designated area on the screen is close to the human body.

[0060] For example, take a capacitive touch screen as an example. When the human body is in contact with the capacitive sensing area on the screen, the electric field of the human body will form a coupling capacitance with the surface of the touch screen. For high-frequency current, the capacitance is a direct conductor, so the human body will absorb a large Small current, this current is supplemented by the electrodes of the touch screen, this current can be called supplementary current. In essence, when the...

Abstract

An embodiment of the invention discloses a screen control method and a terminal. The screen control method comprises that in a conversing or call-initiating process of the terminal, whether the distance between a designated area and a human body is larger than a distance threshold value is determined based on electric signals generated by a screen of the terminal when a designated area on the screen approaches the human body; and the screen is controlled to be turned off if the distance is not larger than the distance threshold value, and the screen is controlled to be turned on if the distance is larger than the distance threshold value. By means of the technical scheme provided by the embodiment, the off and on of the screen can be controlled accurately in the conversing or call-initiating process of the terminal.

Description

technical field [0001] The present invention relates to the field of touch screen technology in the field of terminal technology, in particular to a screen control method and a terminal. Background technique [0002] At present, touch screen terminals have become the mainstream terminal for applications, but when users use the terminal to make calls, the terminal screen is in contact with the face or head of the human body for a long time, which may easily cause erroneous operations. The solution adopted in related technologies is generally to use light sensing technology to control the on and off of the screen. On and off. During a call, the light sensor on the front of the terminal perceives the surrounding light conditions. When the terminal is close to the human body (such as the ear) at a certain distance, it senses that the light becomes dim, and the control screen will be turned off. On, the control screen lights up. [0003] However, the light sensor lacks a quant...
